During the year 2023, regular optical observations of Near-Earth asteroids (NEA), which could be potential candidates for parent bodies of meteoroid streams, were conducted. Observations were carried out using the telescope SHAK of the RI "MAO." The processing of observations resulted in a catalog of 494 topocentric positions of 19 NEAs in the range of (11-16.0)mag. Catalog positions were submitted to the MPC IAU database. In 2023, meteor observations were continued using a complex of 2 meteor telescopes (f=50mm, f/1.2) equipped with broad-band blue and red filters for calculating the color index of meteors. Software for obtaining meteor brightness curves was developed. The results of photometric reductions yielded equations linking the instrumental system to the BP/RP system of the Gaia EDR3 catalog. Observations of radio meteors were conducted using the M-FM network with 2 stations located in Mykolaiv and Voznesensk (Mykolaiv region) and the M-GRAVES network with 2 stations located in Ivano-Frankove. A report was presented at a conference in Kyiv based on the observation processing results. Improvements to the software were made to determine the time and frequency of meteor signals and to calculate the radial velocity of meteors from radar observations at GRAVES and FM broadcast frequencies. The results of radio observations of Perseids and Geminids meteor streams in August and December 2023 were submitted for publication on the RMOB website. 3 articles were published in specialized journals, 2 articles were submitted for publication in journals indexed by Scopus and 3 presentations were made at international conferences. 2 applications for copyright registration were submitted.
